I have now this Asus connected to the normal, rebuild and upgraded computer
with quite new hardware (Z790 mobo, i12 and Arc A750 gpu). A750 does have HDMI
and DP ports, but no DVI-D. Asus receives input from HDMI connected, which also
wakes up the monitor with a bip at boot. With only a Display Port connection,
Asus receives no signal from this gpu/computer, neither when I select this
manually.


The other MSI/Nvidia computer is relocated and connected to its normal, simpler
monitor Philips 244E. It works as it should with DVI-D connection, and I have
also tested it with the same USB boot installation session.

However, I posted this bug because as long as the USB boot installation menu
displayed ok over DP to Asus, I found it illogical it should loose this
connection during the selected install or upgrade session.


Does the Asus have a

I don't remember if Asus ever has had a firmware upgrade, possibly not via
Linux I would guess.

The benefit with the Asus connections is its flexibility with new and old
hardware and for multimedia work. I use also testing my authored and burned
BD/DVD discs in standalene players connected via HDMI,
